Thanks Mark,

That is what I was looking for, but I was having trouble getting the actual ascmd.exe file. From searching I founf it is in a sample package you can download from MicroSoft, but all the links to it I found were broken, and referenced VS 2005. Searching the MS site for it got no hits. We finally found some sample package for Visial Studio 2005 (we are using 2008). you have to get the folder and compile the project (based on whether you will run it on 32 o64 bit) and need SDK installed on the system you will compile this on.

Then moved the ascmd.exe file over to the server and I can now run my XMLA scripts from the command line.
